[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] refer to Figure 1-4 This invention provides a land-based testing fixture for an underwater separation device, comprising an upper support plate 1 and a lower support plate 2 fixedly connected to the top of the upper support plate 1. The upper support plate 1 and the lower support plate 2 form a circular structure. Several test components are evenly spaced along the circumference of the inner wall of the circular structure. An annular cavity 3 is formed between the upper support plate 1 and the lower support plate 2. Several transmission components and a drive component are arranged in the annular cavity 3. The test components are connected to the drive component through the transmission components. A limit adjustment component is provided on the transmission component. The transmission component is slidably limited to the annular cavity 3 through the limit adjustment component. A separation device test piece 4 is arranged in the middle of the circular structure, and several test components are respectively arranged corresponding to the separation device test piece 4.

[0026] The scheme is further optimized by providing several through slots 5 evenly spaced along the circumference on the inner sidewall of the annular structure. The through slots 5 are connected to the annular cavity 3. The test assembly includes a test rod 6 with one end slidably connected in the through slot 5. The other end of the test rod 6 is fixedly connected to a test head 7. The end of the test head 7 away from the test rod 6 is correspondingly set with the test piece 4 of the separation device. A connector is provided at the end of the through slot 5 near the annular cavity 3. The test rod 6 is detachably connected to the transmission assembly through the connector.

[0027] The test rod 6 is slidably connected in the through groove 5. Several test rods 6 synchronously drive the test head 7 to move towards the test piece 4 of the separation device and contact the test piece 4 of the separation device. The test head 7 applies force to the connecting piston on the test piece 4 of the separation device to test the test piece 4 of the separation device. Several test rods 6 can perform pressure tests on test pieces 4 of the separation device with different numbers of connecting pistons. At the same time, the sliding setting ensures that the test device is applicable to test pieces 4 of different specifications and sizes of separation devices, and has a wide range of applications.

[0028] The scheme is further optimized. The connecting component includes a first bearing 8 fixedly connected in the through groove 5. The first bearing 8 is coaxially fixedly connected to a threaded rod 9. One end of the test rod 6 located in the through groove 5 is provided with a threaded groove 10. One end of the threaded rod 9 is threadedly connected to the threaded groove 10. The other end of the threaded rod 9 extends into the annular cavity 3 and is fixedly connected to a connecting plate 11. The connecting plate 11 is detachably connected to the transmission component.

[0029] The threaded rod 9 is connected to the transmission assembly via the connecting plate 11. The drive assembly drives the threaded rod 9 to rotate via the transmission assembly. When the threaded rod 9 rotates, it drives the threaded test rod 6 to slide. Specifically, the cross-section of the sliding connection between the test rod 6 and the through groove 5 is rectangular to ensure that the test rod 6 can slide stably in the through groove 5 when the threaded rod 9 rotates. At the same time, a sealing ring is provided on the through groove 5 to prevent the test rod from falling off.

[0030] The scheme is further optimized. The transmission component includes several sliders 12 that are slidably connected in the annular cavity 3. The sliders 12 are located between the drive component and the connecting plate 11. A through hole 13 is provided on the slider 12. A second bearing 14 is fixedly connected to both ends of the through hole 13. A bearing tube 15 is coaxially fixedly connected to the second bearing 14. One end of the bearing tube 15 extends out of the through hole 13 and is provided with a limiting component. The limiting component is limitedly connected to the connecting plate 11. The other end of the bearing tube 15 extends out of the through hole 13 and is fixedly connected to a support rod 16. The support rod 16 is connected to the drive component for transmission.

[0031] A carrier tube 15 is rotatably connected to the slider 12. One end of the carrier tube 15 is connected to the connecting plate 11, and the other end is connected to the drive assembly. The drive assembly drives the carrier tube 15 to rotate, and the carrier tube 15 drives the connecting plate 11 to rotate, thereby realizing the drive assembly driving the connecting plate 11 to rotate, thus realizing the drive of the test rod 6.

[0032] The scheme is further optimized. The limiting component includes a limiting plate 17 fixedly connected to the bearing pipe 15. The end of the limiting plate 17 away from the bearing pipe 15 has a snap-fit ​​groove 18, which is correspondingly set with the connecting plate 11. Two brackets 19 are fixedly connected to both sides inside the limiting plate 17. Buckles 20 are hinged on the brackets 19. One end of the buckle 20 is fixedly connected to a locking block 21, which is correspondingly set with the snap-fit ​​groove 18. An electric telescopic rod 22 is fixedly connected inside the support rod 16. The telescopic end of the electric telescopic rod 22 extends into the bearing pipe 15 and is fixedly connected to one end of a push rod 23. The other end of the push rod 23 extends into the limiting plate 17 and has a limiting groove 24. The other end of the buckle 20 has a limiting block 25, which is adapted to the limiting groove 24.

[0033] When the slider 12 is moved, the electric telescopic rod 22 is in a retracted state, which drives the two hinged buckles 20 to be in a retracted state. The shape of the locking groove 18 is adapted to the shape of the opening of the connecting plate 11. When the connecting plate 11 is connected to the locking groove 18, the electric telescopic rod 22 drives the two hinged buckles 20 to rotate so that the locking block 21 abuts against the locking groove 18. When abutting, since the connecting plate 11 is connected to the locking groove 18, the locking block 21 also abuts against the connecting plate 11. Furthermore, two corresponding recesses are provided on the inner wall of the connecting plate 11 and the inner wall of the locking groove 18. The locking block 21 is locked in the recess, thereby realizing the limiting connection of the connecting plate 11 and the limiting plate 17.

[0034] The scheme is further optimized. The drive component includes an annular toothed plate 26 rotatably connected to the bottom of the annular cavity 3. A first bevel gear 27 is fixedly connected to the top of the annular toothed plate 26. A second bevel gear 28 is coaxially fixedly connected to the end of the support rod 16 away from the slider 12. Several second bevel gears 28 mesh with the first bevel gear 27 respectively. A transmission shaft 29 is rotatably connected inside the annular cavity 3. A gear 30 is coaxially fixedly connected to the transmission shaft 29. The gear 30 meshes with the annular toothed plate 26. A motor 31 is fixedly connected to the bottom of the lower support plate 2. The bottom of the transmission shaft 29 extends out of the lower support plate 2 and is fixedly connected to the output shaft of the motor 31.

[0035] The motor 31 drives the transmission shaft 29 to rotate, and the transmission shaft 29 drives the ring gear plate 26 to rotate through the gear 30. The ring gear plate 26 drives the fixedly connected first bevel gear 27 to rotate. When the first bevel gear 27 rotates, it drives several meshing second bevel gears 28 to rotate. When the second bevel gears 28 rotate, they drive the test head 7 to move, thereby realizing the test of the test piece 4 of the separation device.

[0036] The scheme is further optimized. The limit adjustment component includes a toggle rod 32 fixedly connected to the top of the slider 12. An annular groove 33 is provided at the top of the upper support plate 1. The top of the toggle rod 32 extends out of the upper support plate 1 through the annular groove 33 and is fixedly connected to a fixing block 34. The bottom end of the fixing block 34 slides in contact with the top of the upper support plate 1.

[0037] By manually moving the fixing block 34 to slide on the top of the upper support plate 1, the actuating rod 32 slides in the annular groove 33, driving the slider 12 to make a circular motion, adjusting the position of the slider 12, so that the limiting plate 17 and the connecting plate 11 are connected accordingly.

[0038] The design is further optimized by providing a threaded hole 35 on the fixing block 34, with a bolt 36 connected to the threaded hole 35 by internal thread.

[0039] The fixed block 34 slides along the top of the support plate 1. When it is selected to a suitable position, the threaded end of the bolt 36 is made to abut against the upper support plate 1 by tightening the bolt 36, thereby limiting the fixed block 34 and further limiting the slider 12.

[0040] The scheme was further optimized so that the number of transmission components did not exceed the number of test components.

[0041] The test component is connected to the drive component via a transmission component. The transmission component connects the test component and the drive component. The number of transmission components can be the same as the number of drive components, with each transmission component corresponding to a drive component to control the drive component. The number of transmission components can be less than the number of drive components, but not less than four. The test component at the corresponding position is selected by moving the transmission component, and the test component at the corresponding position is controlled by the drive component to perform pressure tests on the test piece 4 of the separation device with different numbers of connected pistons.

[0042] The design was further optimized by fixing several lifting rings 37 at equal intervals along the circumference at the top of the upper support plate 1.

[0043] During testing, the entire testing device is lifted by connecting the lifting ring 37 with a rope. After being lifted, the test is conducted to facilitate observation of the separation and detachment process of the two parts of the underwater separation device shell.
